    Raised vs Flat Panels

    I've built many raised panels for cabinets and etc. now I have a need to put flat panels in my rail and stile door frames. I normally use 4/4 ruff cut milling it down to 3/4 oak and I'm really puzzled on how to do the panels without just planning the panels down from 3/4 stock. I would hate to waste good 3/4 stock making flat panels. I try not to use ply but might consider it if need be. Resawing? maybe but I could see having problems glueing and getting them flat.
    How and what do you folks use for your flat panels?

    I do them with plywood. It is nice and stable for a thiner panel. Although I don't like to go thinner than a half inch because the cabinet will sound like a drum.

    I don't have a ton of experience with panel glue ups so I stick to what I can do easily unless a customer wants something special.

    That being said I have always loved the flat panel doors that are a raised panel backwards. It really smacks of quality. Its almost borderline excessive; so when I see it it makes me smile. Maybe thats the way you should go since that is what you do alot of. That way the panel is still 3/4" thick.

    veneered MDF is my choice. Perfectly flat, very solid feel and sound, and no telegraphing. Also, MDF core usually has a thicker outer veneer than veneer core.

    I use shop-cut veneer pressed onto 1/2" BB ply. I typically put a rabbit around the back so before I veneer I put a hardwood "frame" around the ply using the same species (and preferably from the same board) as the veneer. Takes a bit longer but makes a really nice job. Allows you to get a pretty much full thickness panel without wasting as much stock.

    I like the idea of reversing the raised panels so the raised part is on the inside.
    There's a router bit for it or simply make the panel edges thinner on the tablesaw.

    Unless this is heirloom furniture, go with the ply. The cherry veneered MDF I used on my kitchen project was beautiful, very reasonably priced when you consider how little waste there was, and it was very consistent in thickness (except for 1 thin sheet.)

    We usually use veneer core ply or veneered MDF core for 1/4" thick flat panels in 3/4" thick doors at work. Solid wood below 3/8" can become problematic as it doesn't take much sticking it make it crack and split. I'm sure many will tell you they do this all the time it it has worked out fine, and I say good for them and their good luck, but in general very thin solid wood panels are prone to problems. When the doors are a bit thicker we run solid panels with a cove profile to the back side, flat panel to the front, but that's usually in at least 1" thick doors with a 5/8" thick panel.

    I suppose you can run a 3/8" thick solid panel with the flat face forward in a 3/4" doors, but that's tough to resaw out of 4/4 stock, and again not necessarily the most stable thing long term.

  8. I recently finished my kitchen doors and drawer faces. I did them out of elm. Plywood not easy to get in elm. Using 4/4 I jointed one face and one edge. I then skip dressed the opposite face(just shy of 1" thick) and ripped final edge on my table saw. Then I resawed to approximately 7/16. I skip dressed the bandsawn faces (easier to see if joints fit tight when you dry fit your pieces)and jointed the ripped edge. They make a real nice book match this way.

    I then glued the panels up. Then have a tendency to pop out of the clamps even with minimal pressure. What you need to do is to put clamps above as well as below the panel.Force a large enough wedge, with waxpaper on the bottom, under the middle of the top clamp where the joints meet. This will hold the panel flat while it dries. The waxpaper prevents the wedge from sticking to the panel. Then plane or surface sand to your finish thickness.

    This worked well on all the 28 drawer fronts and doors.

    Gives you 1 more option.

    Good Luck

    There, as you can see, are many advocates for plywood panels. However, if you want a "top quality" door, mill the solid wood panels down to 1/2 or 5/8, rabbet the backs and treat them as you would any other solid wood panel.

    Depends on the look you want. One advantage to ply is that you can get sequential sheets and cut the panels for a nice consistent pattern. On the other hand, using solid wood gives a more random look that is usually a better color match to the door frames. We do lots of each. I build doors to 13/16" as standard, so a flat reverse raised panel is about 0.6". I'm not so wild about thinner solid wood panels. They react faster to MC changes. But if the joints are sound, they seem to do OK.

    I beg to disagree. "Top quality" doesn't require solid wood, nor does solid wood indicate top quality.

    The one kitchen I did with ply panels, was done by laminating together two sheets of really nice 1/8" RO ply. (beautiful sliced veneer) That way I had an *A* side inside and out.

    IMO, it was as much work to cut out for nicest grain pattern and laminate the two ply sheets, as it would have been to glue up 1/2" thick solid panels and rabbet the backs. Unless you can get 1/4" ply with both *A* sides, those *B* or *C* insides will look a bit shoddy.

    Oh yeah? Sez who? Them's fightin' words. OK, maybe you have a point. But I would stick with my comment to this extent: A "top quality" door cannot be built with "off the rack" plywood. At least not in my world. In yours, the rules may be different. I only use manufactured plywood panels when I'm trying to cut costs. If I want "the best" laminated panels because I need to do something with veneers that would not be suitable to solid wood construction, I usually lay up my own panels. But again, that's just me...

    Hi guys, I'm new to the forum and thought I would jump in.
    For shaker style doors, or the flat panel look, I like to use a 1/4" substrate.
    I veneer both sides with either the same species or a contrasting one .

    I think the word is "substrate".
